Updated:(MyFoxBoston.com) -- Boston Marathon bombing survivor Rebekah Gregory lost her left leg from the knee down in the explosions.
After court on Wednesday, she posted a letter to Dzhokhar Tsarnaev on her Facebook page.
Gregory says was scared of him, until now.
The letter reads, in part:
"Today, all that changed. Because this afternoon, I got to walk into a courtroom and take my place at the witness stand, just a few feet away from where you were sitting. I was walking -- did you get that? And today I explained all the horrific details, of how you changed my life, to the people that literally hold yours in their hands. That's a little scary right?"
She signed the letter, "Someone you shouldn't have messed with."
It is now going viral on Twitter and Facebook. Read the full post here.
